CAP LINING MACHINE Filed Sept. l, 1928 9 Sheets-Sheet 9 E FR Patented Aug.. 2, 1932 'mi c 'T 0F Fil .EDWN V. SWANG-REN, OF MAYWOOD, ILLINOIS, ASSIGNOR 0F ONE-HALF TO WALTER N. STEVENSGN, 0F EVANSTON, ILLINOIS CAP-LINING- MACHINE Application led September My invention relates to a machine which is designed for the rapid commercial production of finished paper-lined caps or tops such as are used as closures for various kinds of ars and bottles, and operates upon strips of paper supplied to the machine to cut out the lining disks, and then apply the disks to the caps or tops which are automatically fed into position to receive them, the lined caps being then discharged from the machine. The object of my invention is to provide a machine which by reason of certain novel features in the construction and arrangement of parts and members whichl have devised for the purpose, as hereinafter described and explained, shall operate rapidly and accurately to accomplish the ends in view, and be particularly suitable for continuous hard service. My invention resides in the novel combination of cooperating members and mechanisms which constftutes my cap-lining machine, and certain novel combinations and sub-combinations of mechanical parts and elements relating to the mechan" sms for feeding the paper strips from which lining disks are cut, the mechanism for cutting the disks, the mechanisms for introducing` the caps inte the machine and positioning them into position to receive the l? ners, the means for assembling the caps and liner disks, the means for discharging the lined caps, and the actuating means by which the various parts of the machine are operated in synchronism. In the appended claims, I have i more particularly set forth the essential elements of my invention, it being understood, however, that variations and modifications of construction and arrangement of parts of the machine, as by the substitution of equivalent elements and mechanisms for parts specifically described are possible, without departing from the spirit of my invention, and .l therefore intend my claims to be construed to include all equivale-nt elements within the true scope of my invention.

Like reference characters indicate like parts in all t-he figures of the drawings.

First describing briefly and generally the construction of the machine, the caps t` o which the paper disks are to be applied are supplied by an operative in inverted position to a feed chute from which they pass to a rotating table. rihis feed table delivers the caps to one end of a feed belt from which they are removed at the other end by an intermittently rotating turret or star wheel which transfers them int-o the orifices of a cap disk conveyor having a synchronous movement. This disk carries the caps in a circular path over the upper surface of a supporting table to a working point into alignment with and immedi ately below a die mechanism for cutting out liner disks from a strip, or a plurality of strips, of paper led into its path by suitable intermittently-actin g paper feeding mechanism. lith this die mechanism is associated a plunger device which forces the liner di immediately after they are formed into the caps, aft-er which the caps are carried by the cap conveyor over an orifice in the supporting table, through which they pass to a transfer belt which transfers them to an inspection belt where they may be inspected and from which they are delivered to a storage receptacle.

Describing now the specific construction of l the machine as illustrated in the drawings,

it may first be stated that the principal members of the machine frame are a base plate A, having a lateral extension B on the left side of the machine to provide a motor support and a rearward extension C to support a pedestal upon which the paper reels are mounted; a right side leg casting formed with front and rear legs connected by plate and flange elements appropriately designed to afford 'l bearings and other supports for the moving and stationary parts of the various inecnan nisms; a left side leg casting ll likewise formed with front and rear legs and pro viding supports for various parts; a bed plate or table F, and various other bracket members and supporting parts secured to those mentioned which will be referred to later as the description proceeds.

The feed table 1 of the machine, which is a thin disk continuously rotated by actuating connections hereinafter to be described, is mounted in a feed table bracket G secured to the front of the left side leg casting E b-efore mentioned, near the top thereof,-see Figs. 1 and 5. Immediately below the feed table and extending tangentially of its rear side towards the center line of the machine is a feed belt 3, engaging roller 4- fixed to shaft 5 journaled in the bracket 2 before mentioned and a roller 6 fixed to a short shaft 7 rotatably mounted in a hub 8 formed on bearing bracket H at the front of the machine. The feed belt runs in a shallow groove formed in a plate 9 which is suitably supported by a pair of cross-strips 9 and bracket strips 9b, one pair of bracket strips being secured to the frame bracket G, and the other pair to a post 2 formed on said frame bracket, and is maintained taut by a belt tightener consisting of a tensioned rocking lever 10 carrying an idler roller 11 engaging the belt. A pair of rails 12-12 adjustably secured through slotted L- shaped lugs 12 to said cross-strips 9a and also secured to a feed chute member 13 arranged immediately above the feed table serves to guide the train of caps to be lined on their way from the feed table to the succeeding mechanisms. The rails 12-12 are continuous with the side members of the chute and e5:- tend conceutrically over a portion of the table,

the chute being open at the bottom over the feed table. At its front or feeding end the sides of the chute are connected by a bottom member forming a. trough wit-hin which the caps can be arranged and manually supplied to the feed table.

The feed belt 3 is arranged to convey the caps upon it to a position at the inner end of the cap guide-way, at which point each one of the line of caps which successively becomes the foremost cap is blocked by a vertically reciprocating stop linger 14 projecting downwardly from the horizontally bent upper portion 14a of a lift rod 15 mounted to slide vertically in bearings in the framework of the machine. inasmuch as the feed belt has a continuous movement, the frictional drag of the belt during the period which the foremost cap is blocked by the lowered stop finger extending into it closes up all gaps in the line of caps, and as soon as the stop linger shifts to clear the rear wall of the cap, the latter is shifted forwardly by the belt a short distance, uniform in the case of each cap, onto a turret plate 200 secured to the top of the bearing bracket F before mentioned, and into the path of a turret or star wheel 16 which is connected to a vertical shaft 17 journaled in bearings formed in said bracket, and is arranged to be intermittently rotated as hereinafter describech-see Figs. 5 and 8. The downward movement of the stop linger 14 after the forward cap has moved from beneath it, brings it into similar engagement with the next succeeding cap. The turret plate 200 is notched as indicated at 2001, Fig. 14, to accommodate the inner loop of the belt, and is cut away or peripherally notched, shown at 200" on the side next the center of the machine, so that as the caps are pushed by the star wheel around its axis in the direction indicated by the arrow on Fig. 5, they may drop downwardly from the plate. rlhe caps on the plate are constrained to move in a circular path by the circular wall 19 of a cap member 20 secured to the top of the bearing bracket F, and are shifted in successive steps until they severally arrive at a position of registration with the orifices of an intermittent-ly rotated oriiiced cap conveyor 21, the upper face of which lies in a plane immediately beneath that of the plate 200. A downwardly inclined arcuate spring 20, secured to the cap 20 immediately above and in the path of the caps, is yieldingly cammed upward by the successire cans as they advance towards the peripheral opening in the turret plate, and as the turret wheel comes to rest the spring serves to snap the cap which has come into registration with such opening downwardly into the orifice below it in the cap conveyor.

The cap conveyor, as illustrated, (see Fig. 8) is a flat disk 21 secured to a short hollow vertical shaft :22 journaled in a. hub on the bed plate member F of the machine frame, and is given an intermittent movement, as hereinafter explained. ln the present inp stance the shaft 22 is formed with a iianee 222t at its top, seating in an annular recess at the top of its bearing in the hub, and above the disk 2l is provided a ring` 2i l i through screws engaging threaded seats in the flange clamps the disk to the shaft. To the lower end of the shaft 22 are secured a Geneva wheel 201 and a gear wheel 202 meshing with a pinion 203 iii-sed to the shalt 17 before mentioned, by means of which (through operating connections later to be described) the star wheel 16 and cap conveyor 21 are given a synchronous movement which brings the notches of the turret or star wheel successively into registration with the orifices 25 of the cap conveyor at periods of rest, permitting the caps to drop successively out of the path of the star wheel into the orifices of the conveyor and upon smooth face formen upon the bed plate member F before mentioned constituting a conveyor table.

As illustrated in Figs. 8 and 9, the criiices of the cap conveyor are formed in removable ller plates 2la in order that by interchange of sets of filler plates formed with openings of diderent size, the machine may be adapted to operate upon caps of differentdiameters.

t may here be explained that to avoid accidental injury to the star wheel mechai llll An which otherwise might occur from a cap jamming in the star wheel should it fail to completely enter a notch thereof from between the rails 12-12 of the feed passage, the shaft 17 is equipped with a flange member 304i formed with a pair of opposite radial ribs 305--305 which are wedge shaped in cross section, and the star wheel is secured to collar 30W-305a which is formed with com- 'i Si) plementary radial grooves. By means of a spring 306 confined between a nut 307 on the upper end of the shaft 17 and a loose washer bearing on the upper face of the star wheel, (see Fig. 8) the ribs 305 are yieldingly held in the mating grooves of the collar lined to the star wheel, so that the shaft and star wheel will rotate as one under normal conditions, but under positive resistance due to the jamming of a cap, the star wheel will be cammed up-ward to permit rotation of the shaft alone and injury thus avoided. It has been found in practice that the jar produced by the snapping of the star wheel upwardly and down again when jam occurs serves in most cases to dislodge the cap which is jammed, and the regular feeding operation is immediately resumed.

After each cap has dropped into its particular orifice in the cap conveyor, it is carried around upon the cap table to a pointof rest in its path of travel,in the present instance, but not necessarily, a diametricall y opposite point,-at which point of rest it comes into alignment with the member of the liner-disk cutting and liner-seating mechanisms.

The fixed die member 25a of this mechanism is seated in a block 26 removably secured above an interposed spacer plate 26 to the bed plate member F of the machine frame, see Figs. 5 and 9. it is obvious that by removing the securing screws which hold the block 26 and spacer plate 26a to the frame (the ring 2d of the cap conveyor being first removed), the associated members, including the lower die member, may be removed to permit interchange of parts. The movable member is a punch 27 the working portion of which is tubular in form, secured to a removable block 28 forming part of the crosshead 29 of a movable frame 30 mounted to have a vertical sliding movement. This movable punch frame includes the crosshead 29, a pair of vertical guide rods 3l3l, and a yoke 32 secured to the lower ends of the guide rods,-see Figs. l, 6 and 9,-and is reciprocated by means later to be described. ln the present instance,-see Figs. 6, 8 and 9,-the rods 3l have long bearings in a. pair of tubular guide brackets 33 which are bolted to opposite sides of the bed plate F, and are cut away to clear the cap conveyor,-see Fig. 5. To further guide the punch member, the block 26 secured to the bed plate F is equipped with posts 3a and the block 28 secured to the movable frame is formed with sockets engaged by these posts, (see Fig. 9) so that accurate registration and engagement of the punch and die members are assured.

By reciprocation of the punch frame and the tubular punch member carried by it, lining disks are successively cut out from the strips (or single strip) of paper intermittently fed between the punch and die members during an interval of rest in the movement of the cap conveyor, and the severed lining disks are immediately thereafter forced into place into the cap at the time below the die, by means of aI liner-seating plunger 35 secured to a. vertical stem 36 which is slidingly mounted coaXially of the die members in the cross head 29 of the movable frame,see Figs. 8 and 9. In the present instance, to provide for change of punching members and liner-seating plungers, the stem 36 consists of interlocked upper and lower members, a and 2),-see Fig. ll. The front side of the cross-head is formed with an opening opposite the joint in the plunger stem, and it is obvious that by removing the screws which secure the block 28 to the cross head the block and parts associated with it may be removed as a whole. To prevent the plunger from dropping down into the die 25a during removal, a hole is drilled through the lower portion b of the plunger stem, into which a pin may be temporarily inserted.

Near its top, and opposite a recess in the rear side of the cross-head, the stem 36 is formed with a rack.' intermeshing with a toothed segment 37 secured to the inner end of a. shaft 38 which is journaled in bearings on said cross-head. The outer end of said shaft 38 carries a pinion 39 meshing with a rack plate l0 which is slidingly mounted in a portion of the bearing bracket in which the shaft 88 is journaled7 and is yieldingly connected with an actuating rod il which slidingly passes through a bore iormed in it, by means of a. coiled compressing spring 42 interposed between the bottom of the rack plate and a collar L3 secured to the rod below such plate,-see Figs. l and 1l. The actuating rod 4l is pivoted to the free end of a rocking arm lll by which it is given a vertical movement through a cam roller l5 intermediately pivoted on such arm and arranged to engage a. cam groove 46 formed in the side face of a gearing member later to be described,-see Fig. l2.

Inasmuch as more or less loose motion in the connection for reciprocating the linerseating plunger will inevitably develop in use, and the downward thrmv of the plunger would tend to batter the cap below the plunger unless prevented., l have provided a buffer which can be quickly and accurately adjusted to prevent this injurious eiect. This buffer consists of a leather washer 3G near the top oit the upper section a of the plunger stem, backed by an adjusting nut 361 on said stem7 the leather member being arranged to bring up against a stop surlace on the top of the cross head 29 and sustain the downward stroke of the plunger at the exact point necessary to avoid injury to the cap.

In order to accommodate the n schine for work upon caps having domed heads, or heads having an easily marred portion, l have provided below tl elements a remi@ movable filler plate l5() which is interchangeable with li sired contour adai particular caps to be ope' Ued upon.

The intermittent rotary movement of the cap conveyor shitts the caps successively into a position of registration at a subsequent interval oi rest with a discharge opening or gap 151 in the conveyor table through which the caps may fall7 one one7 onto upper reachotcontinaouslymo g endl sbelt conveyor or transfer belt 1 '7 gs. 5 and 6.

Inasmuch as the o yhe cap conveyor must be but -ly larg` fn nie-.ineter than the caps in order to ensure correct alignment under the die and plunger mechanisms it is desirable to provide an ejector mechanism for positively 'forcing such cap downwardly from its -oriiice through the openingr in the conveyor table7 in case it should fail to fall therethrough by gravity. This ejector consists ot a plunger head 210 on the lower end of a rod 2l()a which is carried by parallel arms 2li-212 which are pivoted to the punch frame 30, see Fig. 3. A portion of the arm 211 extending rearwardly of its pivot is connected by a link 2li with the machine frame7 so that the vertical movement of the punch frame imparts a multiplied movement to the plungcr,-see Figs. 3 and 6.

rlhe transiter belt 1li' above mentioned is mounted upon a driving roller i8 secured to a longitudinally extending shaft t9 through which it is driven and an idler roller 5() jonrnaled in bearings carried by a stationarily supported frame plate 5l,-see Figs. l, 2, (i, and 7. ns the caps are carried. on the face of the belt towards the right of the machine they are cammed rearwardly by a stationarily supported Ofuide linger 52 and drop onto the upper reach oi a broad inspection belt 53 which has a slow intermittent movement and from which the caps pass to any convenient receptacle. rlhe relatively slow intermittent movement of the inspection belt, in connection with action of the guide linger on the continuously moving single line of caps on the more rapidly moving transfer belt, acts to crowd successive caps laterally olil the transfer belt in a somewhat irregular manner, spreading out widely over the surface ot' the inspection belt, so that adequate opportunity for inspection and rem val ot detectively lined caps is 'thereby ali'orded. ln case of a stoppage in the ieeding of caps through the machine, while the die mechanism is cutting out liner disks which pass on to the transfer belt, the paper liners pass under the guide linger and are not delivered to the inspection belt.

rlhe inspection belt 53 is mounted upon a rear driving roller 54: liXed to a shatt 55 which is journaled at its inner end in a bearing carried by the right trame member D and at its outer end in a bearing carried by a frame bracket 5G, and upon a front idler roller which is carried by a long stud 57 secured to the free end of a swinging adjusting arm 58 angularly adjustable upon a clamping bolt 59 by which it may be rigidly secured to the frame. The frame plate 5l above mentioned is secured at one end to the stud 5i" and at the other to the trame bracket 5G.

The mechanism for feeding paper to the liner disk cutting members may now be described. In the present instance two disks oi paper are intended to be placed simultaneously in each cap, and consecluently means for sinmltaneously feeding two str'ps of paper are employed. rEhe upper paper reel 60 and lower paper reel 6l are both pivotally mounted in a pedestal 62 bolted to the extension C of the base plate before mentioned,- see Fig.

lnasmuch as a smooth running and substantial support tor the paper reels is imrno ' pair of supporting bolts 82 portant, and it is also important that means be provided for quickly removing an empty reel and substitut-ing a fresh one, l have devised for the purpose the particular form of assembled bearing unit shown in section in Fig. 13, in which the hub member 68 of the reel is efuipped with a pair of internal spaced bearing rings Get-64a formed with ball races, and a bearing stud 65 is provided which is detachably secured to a socket in the pedestal by means of set screw The bearing ring 64a is of larger diameter than the ring 64 and' is seated in an annular shouldered seat at the outer end of the hub-to the right in Fig. 13. The stud 65 is shouldered, to provide a seat on its' central .portion 65a for a bearing ring 57 formed with a ball race to receive balls by which it is rotatably connected with the ring 64a, and the portion 65a is shouldered to provide a seat on the reducedv end portion 65h for a bearing ring 68 formed with a ball race to receive balls by which it is connected with the ring 6l. The ring 67 is held in place on the stud by a collar 69, and the ring 68 by a washer 68a and nut 58" on the end of the stud. rllhe assembled bearing members together with the bearing stud 65 are retained in assembled relation by means of a ring 70 secured to the inner end of the hub. Y It is obvious that by loosening the set screw 66 the assembled bearing unit and the reel of which it forms a part can be removed as an entirety to permit a change of reels.

From the upper reel the paper runs over an idler roller 71, and from the lower rcel over an idler roller 72, both of which are rotatably mounted in a vertical bar 73 which is secured to a pair of supporting rods i4- 74a secured to the pedestal 62,-see Figs. 3, 4, and 5.

From the rollers 71 and 72 the strips of paper run together betwen a pair of guide rolls 75-75a. then over a guide roll 78, under a guide roll 77, over a gnide roll 78 and under a guide roll 79, all of which are rotatably mounted in a tension frame consisting of a pair of horizontal guide plates 80-81 arranged to be simultaneously adjusted towards and away from the center line of the strips of paper. To this end the plates 80-81 are equipped with oppositely screw-threaded blocks 80';l making engagement with opposite rightvand left screw-threaded sections of a 82 whichnare rotatably mounted in opposite ends of a bracket 83 (see Figs. 4 and 5), the bolts being provided with hand wheels 82;L for turning them,-see Fig. 3,

Forwardly of the front guide roll 79 he strips of paper pass together between lower and upper feed rolls 84 and 85 respectively, both rolls being positively driven and the 1upper roll being tensioned and mounted in bearing blocks 86-86 which may be shifted vertically to release the paper between the rolls. To this end the blocks 86' are slidingly mounted in frame brackets 87-87, and are adj ustably tensioned by springs 88-88 interposed between such blocks and adjusting screws 8SM-88a, and are arranged to be simultaneously lifted against the stressr of the springs by rearwardly extending arms 89 secured to a rocking frame 90 pivoted in.

plate 96 to the front end of the machine,V

where it is discharged and may be removed in any desired manner.

Describing now the operating connections whereby the different mechanisms above described are actuated, the shaft of the motor 97, supported by the extension B of the base plate, is provided with a pinion 98 arranged to mesh with a gear wheel 99 fixed to the left side section of a two-part clutch shaft 100, the right and left sections of which are journaled in bearings in the right and left side leg castings, respectively, see Fig. 7. At the right side of the machine the right section of this shaft 100 is provided with a hand wheel 101 by which it may be manually turned for the purpose of varying the position of con nected parts in making adjustments of certain of them.

The two sections of the shaft 100 are con nected by a clutch 102 (see Figs. 2 and 6) the details of which need not be here explained, which is actuated to connect, or disconnect them by means of an intermediately pivoted hand lever 103, a link 104, and a pivoted yoke 105 straddling one of the clutch elements and arranged to shift it into and out of engagement with the other clutch element.

To the right end of the shaft 100 is secured a pinion 106 arranged to mesh with a large gear wheel 107 fixed to a shaft 108 which is the main power shaft of the machine and is journaled in bearings in the right and left side castings of the machine frame, the lower part of each bearing being formed in a downwardly bowed frame member 109 (see Fig. 1) which is bolted to the right and left side leg members.

Near the center of the machine the shaft 108 carries an eccentric 110 which is connected by a strap and pitman 111 with the yoke 32 of the punch frame, whereby the latter is reciprocated, the ejector rod 210 being actuated by the frame in the manner before described,-see F igs. 1 and 6.

The shaft 108 also carries a pinion 122 arranged to mesh With a pinion 113 fixed to a shaft 114 which is journaled in bearings in the side members of the machine frame,see Figs. 1 and 6. To the face of the pinion 113 is secured a bevel pinion 115 arranged to mesh with a bevel pinion 116 fixed to the lower end of a vertical shaft 117 journaled in bearings formed in a frame bracket 118 bolted to the left side frame member' of the machine frame. Secured to the upper end of this vertical shaft 117 is a crank arm equipped With a roller 119 and multilated locking disk 120 arranged to cooperate respectively With radial notches 120au and arcuate faces 120b in the Geneva Wheel 201 hereinbefore mentioned, and which is secured to the shaft 22 carrying the cap conveyer,-see Fig. 7. Through the gear Wheels 202 and 203 the intermittent movement thus given the cap conveyor is also imparted to the star Wheel 16 so that these two members have the synchronous movement already described.

The cam groove 46 which is arranged to actuate the cam roller for the purpose of actuating the liner plunger 35 mounted in the main frame in a manner already eX- p1ained, is formed on the inner face of the gear Wheel 107.

To the left end of the shaft 114 above mentioned is secured a pear-shaped cam 121 (see Fig. 4) arranged to cooperate with one end of a rocking lever 122 journaled in the left side frame member, the other end being ar ranged to operate the lift rod 15 before inentioned to lift the contact finger 14 at proper intervals.

Upon the left end of the shaft 108 is secured a crank plate 123 equipped with a Wrist pin mounted on a radially adjustable block 123a to vary the length of stroke of a pitman rod 124 pivoted on such pin. rThe pitman is pivoted to a rocking arm 125 carrying the housing and ring member 126 of What is commercially termed a Hort-on friction ratchet (see Figs. 4 and 10), Which includes a ratchet Wheel formed with Wed ge faces and the ring When the members are rotated relatively in one direction and run free when rotated in the opposite direction. The ratchet member 127 of this one-Way clutch, or ratchet, mechanism is fixed to al gear Wheel 128, the hubs of both the att-ached gear Wheel Y and ratchet, and the housing member, being rotatably mounted on a stud 129 rigidly mountedin the frame of the machine.

The gear Wheel 128 is arranged to mesh .n with a pinion 129 secured to a shaft 130, Which is `iournaled at one end in the frame bracket S7 before mentioned and extends across to the right side of the machine. The lower feed roll 84, is fixed to the shaft 130, and this shaft also carries a pinion 131 arranged to mesh with a pinion 132 fixed to the shaft 133 Which carries the upper feed roller 85,-see Fig. 10.

Inasmuch as the moving parts of the intermittent paper feed mechanism have consi derable momentum, I have provided a brake mechanism to steady their movement. 'E his mechanism includes a friction drum 134 engaged by opposite arcuate faces formed on a pair of spring-tensioned brake jaws 135-135 which are pivoted together at their rear ends, and at their front ends are orificed to engage a stationary retaining or supporting bolt 136 secured to the bed plate of the machine,-see Figs. 5, 6, and 10.

At the right side of the machine the shaft 130 carries a pinion 137 which is arranged to mesh with a relatively large gear Wheel 138 fixed to the shaft upon which the driving roller of the inspection belt 53 is mounted,- see Figs. 2, 3, and 7.

The feed belt 3 and feed table 1, and also the transfer belt 47 are continuously rotated by the following train of connections. The left hand section of the clutch shaft 100 carries a driving pulley 139 engaged by a belt 140 (see Figs. 2 and 3) Which drives a pulley 141 fixed to a shaft 142 journaled in bearings formed in theopposite side members of the machine and equipped with a Worm 143 (see Figs. 2 and 3.) The Worm 143 is arranged to mesh With a spirally toothed pinion 144 sccured to the shaft 49 before mentioned, which is ournaled in a front bearing formed in the bearing bracket H and a rear caring formed in the bed plate F of the machine, and has secured to it the driving roller 43 en* gaged by the transfer belt (see Fig. 6).

To the front end of the shaft 49 is secured a sprocl'fet Wheel 145 engaged by a sprocket chain 146 which engages a sprocket Wheel 147 fixed to the short shaft 7 before mentioned, which is journaled in the bearing bracket H and to which is secured the rolle:` 6 through which the feed belt is actuated (see Figs. 1, 5, 6, and 7).

The shaft 5 Which carries the roller 4 and is rotatably mounted in. bearings formed in the feed table bracket G near its front end is a so equipped With a bevel pinion 149 rotatably mounted on a vertical bearing stud carried by the front end ofthe bracket G and to the upper face of this pinion is secured the feed table 1.

rPhe direct connection to the motor of the feed table and feed belt for advancing caps chine illustrated and above particularly described is adapted to apply to two liner disks usually employed, the lower' one formed ot Ya relatively thick material and the upper one a thin close-gr ined material, both parathned in advance, it is possible, by the provision ot additional paper reels and guide rolls, to apply additional liner disks to the caps, three, or four, liner disks being sometimes employed.
